You can, if you want to. Or you can just simply use something like this: # cat /etc/sysconfig/network-scripts/ifcfg-br6 DEVICE=br6 TYPE=Bridge BOOTPROTO=static ONBOOT=yes # cat /etc/sysconfig/network-scripts/ifcfg-eth4.6 DEVICE=eth4.6 VLAN=yes BOOTPROTO=none ONBOOT=yes BRIDGE=br6 In that example br6 has a slave interface, eth4.6, which has access to public IP address. By specifying BOOTPROTO=static (or none) and give no IP address, both interfaces (eth4.6 and br6) will be up with no IP address. So you can have domU with access to public internet but dom0 itself accessable only from private network. Think an L2-switch, and you'll see what I mean. > > Additionally I do not know how to point on them in DomU’s config files, > because new config files are in new format S-expression, which in my case, > cancel all changes I did manually after the start of virtual machines? virt-install creates xend-managed domUs by default, but you don't have to use new format if you don't want to. Just use old-style config. Here's an example: # cat /etc/xen/config/test name = "test" memory = "500" disk = [ 'phy:rootvg/testrootlv,hda1,w', ] vif = [ 'mac=00:16:3E:4D:19:81, bridge=br6' ] bootloader="/usr/bin/pygrub" vcpus=1 Using that config, I can create that domU with a simple "xm create test" -- Fajar _______________________________________________ Xen-users mailing list Xen-users@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-users
